BACKGROUND OF THE DISCLOSURE Field of the Disclosure

The present disclosure relates to a launch tube used to fire an ammunition, such as a gun barrel, and more particularly, to an ammunition-loaded launch tube provided with an ammunition loaded thereon.

Description of the Related Art

In general, an ammunition is composed of a cartridge case and a bullet, and representative devices for firing ammunitions include guns and cannons. In a gun or cannon, a bullet is fired by putting an ammunition into a gun barrel, pulling a trigger, and striking the ammunition with a ball, causing the ammunition to explode. As a result, firing is performed through the process of putting an ammunition into a gun barrel and the process of pulling a trigger.

In the configuration as described above, one gun barrel is continuously used, and firing is repeated while continuously supplying ammunitions. In this case, the gun barrel overheats due to repeated firing, and accurate firing may not be achieved.

SUMMARY OF THE DISCLOSURE

Therefore, the present disclosure has been made in view of the above problems, and it is an object of the present disclosure to provide a novel paradigm different from the conventional configuration of putting an ammunition into a gun barrel and pulling a trigger to fire the ammunition. That is, the present disclosure provides a gun barrel (referred to as a “launch tube”) on which an ammunition is preloaded. According to the present disclosure, bullets may be fired by replacing the launch tube with an ammunition loaded thereon.

In accordance with one aspect of the present disclosure, provided is an ammunition-loaded launch tube including a barrel part having a predetermined length through which a bullet passes when fired; and an ammunition loading part formed to be coupled to one end of the barrel part and having an ammunition chamber having an internal structure matching a shape of a cartridge case, wherein an ammunition is loaded into the ammunition chamber, the cartridge case engages the ammunition chamber, the ammunition-loaded launch tube is mounted on a separately provided launcher, the bullet is fired, and then the launch tube is replaced with a new launch tube.

BRIEF DESCRIPTION OF THE DRAWINGS

The above and other objects, features and other advantages of the present disclosure will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which:

FIG. 1 is an exploded view of an ammunition-loaded launch tube according to the present disclosure;

FIG. 2 is an exemplary mechanism by which a bullet is fired from an ammunition-loaded launch tube according to the present disclosure; and

FIG. 3 shows an example of a rifle equipped with an ammunition-loaded launch tube according to the present disclosure.

DETAILED DESCRIPTION OF THE DISCLOSURE

The present disclosure discloses an ammunition-loaded launch tube including a barrel part having a predetermined length through which a bullet passes when fired; and an ammunition loading part formed to be coupled to one end of the barrel part and having an ammunition chamber having an internal structure matching the shape of a cartridge case. With this configuration, when an ammunition is loaded into the ammunition chamber, a cartridge case engages the ammunition chamber. Thus, the ammunition-loaded launch tube may be mounted on a separately provided launcher, and a bullet may be fired.

Hereinafter, the present disclosure will be described in detail with reference to the accompanying drawings FIGS. 1 to 3 .

FIG. 1 is an exploded view of an ammunition-loaded launch tube according to the present disclosure, FIG. 2 is an exemplary mechanism by which a bullet is fired from an ammunition-loaded launch tube according to the present disclosure, and FIG. 3 shows an example of a rifle equipped with an ammunition-loaded launch tube according to the present disclosure.

As shown in the figures, an ammunition-loaded launch tube 100 according to the present disclosure includes a barrel part 120 and an ammunition loading part 140.

The barrel part 120 is formed in a shape through which a bullet 240 may pass, and is made of a material capable of withstanding load and pressure generated when an ammunition explodes and the bullet 240 is fired. A spiral rifling that induces rotation of the bullet 240 may be formed along the inner circumferential surface of the barrel part 120. In addition, known configurations of a general barrel may be further adopted for effective firing of the bullet 240.

The ammunition loading part 140 is formed to be coupled to one end of the barrel part 120. Preferably, the ammunition loading part 140 and the barrel part 120 are integrally formed for structural stability. However, the present disclosure is not limited thereto, and the ammunition loading part 140 and the barrel part 120 may be formed into a detachable structure. An ammunition chamber 142 is formed inside the ammunition loading part 140. The ammunition chamber 142 is formed into a shape corresponding to that of an ammunition 200. In particular, the ammunition chamber 142 has a shape matching that of a cartridge case 220.

The ammunition chamber 142 is formed in a state in which the ammunition 200 is loaded into the ammunition chamber 142. When the ammunition 200 is loaded into the ammunition chamber 142, the cartridge case 220 is fitted into the ammunition chamber 142, and the ammunition 200 is coupled to the ammunition chamber 142 without being separated.

The launch tube 100 according to the present disclosure having the above configuration is mounted on a separately provided launcher to fire the bullet 240. For example, the launch tube 100 is mounted on a gun or cannon to fire the bullet 240. In this case, the launch tube 100 is mounted on the front of the launcher such as a gun or cannon, and the bullet 240 is fired. In this process, only the bullet 240 is fired through the barrel part 120, and the cartridge case 220 is pushed back by pressure generated when the ammunition 200 explodes and is ejected from the ammunition chamber 142.

According to the present disclosure, the launch tube 100 may be replaced with a new launch tube, and the bullet 240 may be fired continuously. That is, since the launch tube 100 is replaced with a new launch tube after one firing, the bullet 240 may be fired without overheating.

The other end of the barrel part 120 may have a blocked structure. Specifically, a blocking film 160 is formed at the other end of the barrel part 120 to block the other end. The ammunition chamber 142 is formed to be sealed by the cartridge case 220. Accordingly, when the ammunition 200 is loaded into the ammunition chamber 142 and air is extracted from the inside of the barrel part 120, vacuum may be formed inside the barrel part 120. In this case, air inside the barrel part 120 may be extracted by forming a hole in the barrel part 120, sucking air through the hole, and then blocking the hole. However, the present disclosure is not limited thereto, and various vacuum forming methods may be used.

In addition, the blocking film 160 must be destroyed by the bullet 240 when the bullet 240 is fired. Accordingly, since the blocking film 160 must not be destroyed in the process of forming vacuum inside the barrel part 120 and must be destroyed by the bullet 240, the blocking film 160 is preferably made of a material having strength that satisfies these requirements.

When vacuum is formed inside the barrel part 120 in this way, there is no air resistance inside the barrel part 120 when the bullet 240 is fired. Accordingly, the bullet 240 may be fired quickly and stably.

According to the ammunition-loaded launch tube according to the present disclosure, a launch tube is mounted on a launcher, and a bullet is fired. Then, the launch tube is detached from the launcher, another launch tube loaded with an ammunition is mounted on the launcher, and then a bullet is fired. That is, after one firing is performed, the launch tube is replaced with a new launch tube. Accordingly, bullets can be fired without overheating the launch tube.
